IMPROVEMENT CAR AXLE-BOXES.

Specification forming part of Letters Patent No. 198,046, dated December11, 1877; application filed October 16, 1877'.

To all whom it may concern:

Be it known that I, LINDsEY RossITER, of Port Carbon, Schuylkill county,Pennsylvania, have invented a new and useful Improvement in Axle-Boxes,of which the following is a specification The object of my invention isto construct an axle-box for railway-cars so as to retain the packingmaterial within the box, and so as to prevent leakage of oil from thesame. This object I attain in the manner which I will now proceed todescribe, reference being had to the accompanying drawing, in whichjFigure l is a perspective view, partly in section, of my improvedaxle-box, and Fig. 2 a longitudinal vertical section of the same.

A is the box, and B the axle, the latter passing through an opening, a,in the rear of the box, and being reduced in diameter near the frontend, so as to form a journal, b, adapted to the bearing-block d in thetop of the box. The opening a is of the usual elongated shape, so as topermit the box A to be raised vertically when it becomes necessary toremove the bearing-block d.

In order to prevent the escape from this opening of the cotton-waste orother packing material used in the box, I arrange adjacent to the same aplate, D, adapted to vertical guides in the box, and having its upperedge recessed, so as to embrace the lower half of the axle, the upperhalf of which is in contact With the top of the opening a. The plate Dis maintained in contact with the axle by the wedge E.

Immediately in advance of the plate D, and projecting from each side ofthe box into an interior chamber, F, are blocks J, in the inner edges ofwhich are formed concave recesses, as shown in Fig. 1. These blocks donot come in contact with the axle B, but serve to compress against saidaxle the cotton-waste or other packing material in the chamber F, andhold the same, so as to obviate its tendency to work rearward, therebyco-operating with .the plate Din preventing the escape of said packingat the rear end of the box.

If desired, the chamber F may be isolated in a comparative degree fromthe chamber I in the front of the box by a sliding plate, e, adjustablevertically by means of a setscrew, f.

In one or both of the side legs g at the front of the box I form achannel, t, which opens into the chamber I at or near the bottom, andserves as a means of introducing oil into said chamber, the channelbeing closed at the top, under ordinary circumstances, by a sliding cap,m.

This channel is preferable to the usual open- 'ing in the cover of thebox, inasmuch as it prevents the leakage of oil from the interior of thesame, no matter how great the quantity contained therein.

The plate-D has near each edge a recess, n, formed in it, so that saidplate can be bolted to the inner side of an ordinary axle-box, therebyenabling my invention to be applied to the same without requiring anymaterial alteration.

I claim as my inventionl; An axle-box in which the axle is combined witha plate, D, and blocks J J on opposite sides of the journal,substantially as described.

2. The combination of the chamber I of the box with a channel extendingfrom near the top of the box and communicating With the to thisspecification in the presence of two subl v scribing Witnesses.
